In a state of calcination, if it is mixed with strong vinegar, or lime juice, and afterwards dried, if no live Mercury appears it is good; otherwise it is dangerous. Others have said, that if mixed and rubbed with the juice of the radish leaf, till they are incorporated, and then a little lime juice poured over it, and again rubbed and dried, it will be fit for use; and the less live Mercury that is perceptible, the less dangerous it is. To make cups and balls of Mercury, triturate the Mercury well with pounded bricks, in an iron pot, moistening the mixture with water; wash the whole in water, and strain through a moderately fine cloth, till the Mercury becomes perfectly clear like a looking glass. Take equal parts of this purified quicksilver, rock salt, and sulphate of copper, and put them into an iron pot, with strong vinegar or lime juice, and let the whole be well triturated for 7 or 8 hours, when the compound will appear like butter; wash this well in water, that the salt and sulphate be carried off, and the Mercury left behind; take this Mercury and coat over the outside of an unburnt earthen vessel or cup, till it shall be well covered and appear like Mercury; place this in a dish filled with lime juice, and let it remain for a week, then take it out and place it in the sun to dry and harden; when quite hard, it may be used in this way, or it may be filled with water and kept so, till the clay becomes soft enough to be separated from the quicksilver. Milk drank from this cup will have an aphrodisiac quality, and will increase appetite. For the formation of this cup, 9 or 10 tolahs of quicksilver will be requisite, and for the balls one tolah. The Balls.--When the ingredients above-mentioned have, from long trituration, acquired the consistence of butter, balls may be formed of the composition in a fine cloth, and allowed to remain for 7 days in lime juice; then take them out and throw them into a boiling decoction of the Dhatura leaves, allowing it to be well boiled. The balls are then to be taken out of the cloth and preserved for use. In the Maadentezerrubad it is said, that if a small parcel of Mercury be boiled in soup, made from the Bis-Copra, it will become hard. 113 Baboona, or Marehtee: Anthemis Chamomile; a common flower, Akhgwan.
